lDYEING MACHINE.

Application filed December 18, 1923. Serial No. 681,316.

To all whom t may concern.' f

Be it known thatl, yi/Larinna Naomi, a citi- Zen of the United States, and a resident of Brooklyn, county of Kings, and State of New York, have invented certainnew and luseful Improvements in Dyeing Machines, of which the following is a specication.

This invention relates to dyeing machines and has for its primary object to provide an ,efiicient and Vsimply constructed machine for dyeing skeins ofsilk, yarn and other text-ile 4materials, and to this end embodies certain improvements inthe machine shown and described in Patent No. 1,293,514, issued to me on February 4i, 1919.

More particularly, it is the obj eet and purpose of my present improvements to provide a skein dyeing machine which is provided with means for automatically imparting to a plurality of skeins a. bodily to-and-A fro movement in the dye bathas well as a .simultaneous spreading or separating movement between the parallel portions of the individual skeins, thus corresponding closely tothe usual manual or hand operation here-- tofore employed in the art.

in one embodiment of my presentimiention, provide one or more transverse shafts removably supported for longitudinal travel over the dye'vat and each shaft having one' or more skein receiving drums of elongated form xed thereon. By means of suitable mechanism, a unitary reciprocating motion is imparted tothe series of shafts, and in the initial movement of these shafts in one direction the individual shafts are automatically given an axial rotating movement so that. the elongated drums .are partially turned about the shaft axes, thus expanding orseparating the parallel portions ofthe individualskeins which depend from the respective drums into the dye bath contained in the vat.

ln this manner it will be seen that the.

the invention consists in the improveddyeing machine and in the form, construction and relative arrangement of its several parts las `will be hereinafter more 'fully described,

illustrated in the vaccompanyin'g` vdraait/ings Referring lin detailto the ldrawing, .the

dyebath is contained yin the usualvat 5 whichy is of suitable vcapacity in accordance with the 4number of skeins tobe 'simultaneously dyed. Upon the upper longitudinal edges of this vat suitable trackrails are seeured.-

A series'oftransversely positioned shafts,` 7 areprovvided upontheir oppositey ends with the loosely -mounted supporting wheels y8 whichgtravel upon-the track rails lo. These shafts are adapted/to be held in spacedrelation toy eachother by a longitudinally eX- ftending bar v9 having/spaced notches or recesses 10 inthe lower edge thereof toreceive therespectiveshafts. This bar is removably engaged `upon the' central portions of Ysaid shafts yand at one of its fends isiconnectedto suitable actuating vmechanism to be hereinafter described, whereby ,a unitary reeipro-v.

4eating motion is impartedto said shafts longitudinally v`of the :dye-vat. y n

Upon the inner `side of each wheel `8 "a pawlor dog 11Vis looselyy mounted .upon a pin -L2ixed lin the wheel. The free end `of f vthis. pawl is adapted for lengageinent with a vradially projecting rpin; L3 jixed vin theshaft 7. 1A stop pin vor stud 1li isalsofivxed inthe inner 'face of the l.wheel to limit the outward swinging movementof the pawl-.1l-

- Upon one side wall of the va-t 5 .andi adj acent one end thereof a plate or casting 1:5 is 4 vrigidly mounted, said plate at one ofitsends being provided with a suitable bearing for the transversely disposed shaft' 16. kUpon lthis .shaft thebeltwheell? is fixed to receive afdriving belt extending from the motor or' other suitable lsou-roe of power. Upon the opposite end of the .plate l5 the llowerend of ,a .vertically-y disposed 1lever 18 is pivotally fio preferred mechanism but for this purpose I have herein shown an'eccentric 234fiXed upon said shaftvand actuating the arm 2A- which is pivotally Aconnecte'dto. a link 25,v the lower .endpof which is pivoted as atfQG upon the v plate 15. The upper end of thisv linkis conlcentrically secured.

nected by means of a second link 27 to the ylever 18.. i A link member 28 loosely engaged at'one end upon the central portion of the rod 22 connects said rod and therefore the levers 18 and 2O with one endof the rbar 9, said bar being pivotally engaged upon the pin or stud29 fixed in ythel end lof the'link 28. f- Upon each of the shafts 7 one'or'morel elongated skein receiving drums 30 are ec- Any desired number ofthese drums may be'provided upon each vshaft in accordance with the width of the dye vat.

In theoperation of the machine as above described, before' mounting the' shafts 7 in v'operative position upon .the dye vat, the individualskeins of silk or yarn indicated at S, are engagedupon the respective drums Theshafts are now disposed inposition transversely over the dye vat with thev 's vrollers 8 engaged upon the rails and the l s shafts to retain the same in properly lspaced `notched bar 9is engagedk withA the said relation to each other longitudinallyof the vat. `3The individual skeins S thus depend fromthe respective drums into the dye bath contained in the vat. Upon operation of the shaft` 16, an oscillating motion isfim- 1 parted tothe levers 18 and ZOthrough the link and eccentric connections, asl will bel readily understood, 'and .such 'oscillating .45.

movement of the leversis transmitted through th-e link 28 in the form of reciprocating motion toy the bar 9 and the shafts I In the movement of these shafts in one direction, the pawls 11 on thelwhe'elsS engaging'the fiX-ed pinsor studs 13 in the shafts y'l' impart an laxial rotation to the in-v y dividual shafts, thus giving a partial turn Ito `the elongated `drums 30. Accordingly it will be'apparent from reference to Figure 1V of the drawing that in. this turning movement of the drums, as the longer axes of the drums are moved from a vertical to a hori- Zontal'position with respect to the dye vat,

theparallel strands. of the individual skeins yare separated or spreadapart so that the dye 'liquid may thoroughly permeate .all portions vof said skein strands.

shafts 7, said shafts remain stationary While the. Wheels. .rotate with relation thereto.

In the reverse longitudinal movement of the bar 9' andy After the dyeing of the skeins is completed, the bar` 9 is lifted from engagement with the shafts 7 and said shafts with their supporting wheels 8 then removed from their operative'positions upon .the dye vat so that the individual skeins can be easilyremoved from thevr'espective drums 30. In this manner,`the thoroughv and uniform dyeing of the skeins is greatly expedited and the movement of the skeins in the dye bath' which is automatically accomplished by'means of my present invention, very closely corresponds with the costly laborious hand operation heretofore employed.

In the foregoing description lI have particularly referred to an embodimentof my present improvements which is'believed tov liable to get out of order or require frequent repairs. Nevertheless, it will beapparent that substantially the same automaticv action might be obtained by means of other alternative constructions and Iaccordingly reserve the privilege of.' resorting to all such legitimate changes in the form, proportion and relative arrangement of the several parts vas may be fairly embodied within the spirit and scope of the invention as claimed'. f f Y v I claim: 1. In-combination transversely positioned above the bath, supporting Wheels. forv said shaft loosely mounted upon the ends thereof, an elongated skein receiving drum eccentrically .fixed upon the shaft,means for'imparting a bodily reciprocating motion to said shaft longitudinallyv of the-dye vat, and vmeans automatically acting in the initial reciprocation of. said shaft in one direction to impart axialrotation thereto and effect a partial turn of said drum to spread or separate the parallel strands ofthe skein.
